Application filed March 29,1922. Serial no. 547,838.

es tor cou- (ling ma Jets and spindles in winding machinery oi the li e was effected by springs applied to the which he? the detect otan i in relation to the spindle which could not be preven ed. This result cai 'sed faults winding or spooling. The main provide a d come. p

I attain this objectby the mechanism illustrated in the accornpanying.drawing in which I V Figure [is a. detached View in longitudinal section illustrating the first.

Figure 2 is a view in longitudinal section illustrating the second embodiment.

11cc wherein said defect is over- Figure 3 is a detached plan view of a detail. l

Referring to Figure 1' of the drawing. the end of, the wharve 1 has secured to it by means of affiange ring 2; two metal sleeves 3' and 4: which form a hollow space 5. In this space is located an inwardly expanding spring ring 6 (Figure and three balls 7 which are pressed by the spr ng ring 6 into the openings formed in the metal sleeve 3 and serve as carriers.

On the end of the spool 8 is secured concentricallya casing 9 surrounding-the spindle and having externallyan annular groove 10 in which are a number of recesses ll. corresponding in nunibeif with the balls The spindle 12 has a cylindrical boss 13,

Figure 2 which guides the spool conccntrically. 7

When the spool 1s SlICi on the spindle the balls 7 will be ressed back a little. their snap into the groove 10 andatter. a slight turn of the spool 8 into the recesses 11 Inthe exam le shown in Fi 'ure' 2 the.

i i a 7 di lacement and the twist ng of the not of my intention is to spool 8 has at one end a r'ccess and tube 9 which has a circumferential groove and three recesses for the reception of a part'o'f each oftheballs 7.

The balls 7 and the outwardly acting sol-12155 6 are arranged in the hollow'spaoe formed by a recess in the wharve' l and a cap 4 to the wharve and having-holes tor the balls 7 to partially pro ect through.

When the spool is slid on thespindle,the v balls r are pressed inwards and then enter .the groo'vewhereupon after slightly turning the spool the halls snap into the r cesses of sleeve withthe spindle. 7

To uncouple the spool it is best to turn the spool a little and then withdraw it from the wharve.

The halls may also be located in radial holes and employed under the influence of coiled springs which tend to force them out and spools of winding machinery and the like spring influenced balls movably mount-- ed in one of 'the'two parts to be coupled; and means on the other or" said parts adapted to receive and 'be'engaged by portions of said balls. r I
